BC10PopBuf

B = Buffer

C = Calculation functions

The BC10PopBuf function extracts a value from a ring buffer. Each time the latter function makes sure to extract from the circular buffer queue the first data entered and than place it in a variable.

IMPLEMENTATION

BC10PopBuf (Buffer, Element, ErrorCode)

Parameters:

IN/OUT	VARIABLE TYPE	EXAMPLE NAME	DIM
IN	ARRSYS	Buffer	B/W/L/S	Array containing the Buffer
OUT	GLOBAL	Element	L/S	Variable on which you place the value retrieved from the buffer
OUT	GLOBAL	ErrorCode	F	Variable containing the error possibly occurred during insertion of the value

Error

After calling the function if there are any errors the error variable (ErrorCode) take the following values:
0 - No error
1 - Empty Buffer

Example

Extracts an data by the buffer queue and puts it in the “glDato” variable each front of the “gfExtract” variable

MAIN:                 
     IF gfExtract
           gfExtract = 0
           BC10PopBuf (Buffer, Element, ErrorCode)
           IF NOT ErrorCode
              glDato = Element
           ENDIF
     ENDIF

Note

Using this feature is linked to the BC10InitBuf function that initializes the buffer and that must be called at least once before the BC10PushBuf function.
Complementary to this function is the BC10PushBuf function who places a data in a ring buffer queue.
